My understanding is that the tetra-bromo-bisphnol A, which is the usual
retardant is not currently on the ROHS list. However, I believe (but I could
be mistaken) that the scandinavian countries (and Germany too?) are pushing
for all halogenated retardants to be banned.

Hi Kay, and IPC LF Listservers,

So that I close this totally in my mind at least on this list.

All standard Epoxy Glass FR4 (G10-G11), Epoxy Paper CEM grades , and all the
other specialty laminate constructions are using a flame retardant that is
EU RoHS acceptable.  By the way I know there are some circuit constructions
that do not pass UL, CSA etc fire codes and I am not taking those into
account. One CA-JoeF and I worked on, is used in flex circuitry.

So PWB's have nothing to worry about?
 with the exception of lead surface finishes of course.

Thanks thus far Kay,

YiEngr, MA/NY DDave
